Title:
REACTIVE POWER SUPPLEMENTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/085101
Kind Code:
A1
Abstract:
A reactive power supplementing device (1) is provided with a power converter (6) and a converter control unit (7), and supplements reactive power of an AC power system (2) with output reactive power of the power converter (6). The converter control unit (7) is provided with an AC voltage detection unit (21) and an output limit unit (22). The AC voltage detection unit (21) detects voltage information about the AC power system (2) to which the power converter (6) is connected. The output limit unit (22) determines whether or not restriction on the output reactive power of the power converter (6) is necessary, on the basis of the voltage information detected by the AC voltage detection unit (21), and restricts the output reactive power of the power converter (6) when restriction on the output reactive power is necessary.
